Not to discourage you from trying, but the others that have done the
same did not see any tangible benefits. Most of these users were
already using pretty fast disk systems for their repositories, so
perhaps if yours are on a single spindle or something and you have a
lot of RAM for the cache you might see different.

It sounds like when the CollabNet httpd binaries are compiled there is
something special that has to be done to compile in memcache support.
It is also possible the httpd/apr just does not support this on
Windows. The latest CollabNet binaries include httpd 2.2.14. You
could try downloading that version of httpd from Apache and see if it
is compiled differently. Just use the mod_dav_svn that CollabNet
provides with those binaries.
